摘要： A wound closure system includes a device, a sleeve, and a needle assembly. The device includes a shaft and one or more arms movable relative to the shaft between a retracted position and a deployed position. The sleeve is removably positionable about the shaft and is slidable about the shaft to retain tissue between the distal end of the sleeve and the arms when the arms are in the deployed position. The needle assembly includes a base one or more needles insertable through respective needle lumens of the sleeve. The base defines a central aperture for removably positioning the base about the shaft. The base is slidable relative to the shaft and sleeve between a proximal position, wherein the needles are disposed within respective needle lumens, and a distal position, wherein the needles extend from respective needle lumens towards respective arms.

摘要： A stitching device includes a handle assembly and an elongate shaft assembly. The handle assembly includes a main rod and a drive conversion assembly including a cam wheel, a pivot block, first and second links, and a pawl. The pawl is operatively coupled to the main rod, wherein the pawl is configured to engage the pivot block to cause rotation of the pivot block which, in turn, causes reciprocating displacement of the first and second links. The elongate shaft assembly includes first and second blade drive members coupled to the cam wheel. The tool assembly includes first and second jaws and first and second blades. The first and second blades are operatively coupled with the respective first and second blade drive members, wherein axial displacement of the main rod transitions the first and second jaws between open and closed positions and causes reciprocating axial displacement of the first and second blades.

摘要： A surgical clip applier is provided and includes a ratchet mechanism having a rack member connected to a drive channel such that axial translation of the drive channel results in axial translation of the rack member, the rack member defining a first set of teeth along a first side thereof and a second set of teeth along a second side thereof. The ratchet mechanism including a first pawl and a second pawl each tiltably supported in the housing and disposed on respective opposed sides of the rack member; and a buckling spring interposed between the first pawl and the second pawl and constrained in a slot formed in the rack member, wherein the buckling spring is dimensioned so as to bow in one of a proximal direction and a distal direction.

摘要： An endoscopic stitching device includes a handle assembly having a main rod and first and second blade control members, and an elongate shaft assembly having first and second blade drive members, an axial rod, and an end effector. The first and second blade drive members are received in respective first and second grooves of the first and second blade control members and rotated about the first and second blade control members to be secured with a circumferential groove of the first and second blade control members, such that the first and second blade control members are movable with the respective first and second blade drive members. The axial rod is detachably coupled with the main rod for concomitant movement therewith. The end effector includes jaws operatively coupled with the axial rod, and needle receiving blades operatively coupled with the respective first and second blade drive members.

摘要： A surgical clip applier is provided including a clip pusher bar having a flexible tab and a camming plate configured to effectuate closure of the pair of jaws. The camming plate includes a lost motion portion and the flexible tab is configured to engage the lost motion portion during an initial movement of the clip pusher bar to cause the camming plate to move with the clip pusher bar. The flexible tab is configured to disengage from the lost motion portion during a subsequent movement of the clip pusher bar to allow the clip pusher bar to move relative to the camming plate.
